| Summary: | The most failures that occurred in the contacting surfaces were due to the wear in materials of the mechanical parts (products). The lifetime of any machine element or product will be reduced when the rate of wear increases more than the critical value. The main objective of most of the researchers and designers in the industry sectors is to improve the resistance of wear for the machine element (product) that works under heavy working conditions. It can be considered that hardfacing is one of the significant techniques used for the different elements of machines to deposit the hard layer on the contacting surfaces to improve their wear resistance. In this work, St 37 low carbon steel plate with dimensions 120 × 60 × 12.5 mm3 was hardfaced with E1-UM-450 hardfacing electrode under different hardfacing conditions. Taguchi method with L9 orthogonal array was applied to study the effect of different hardfacing parameters. Travel speed, hardfacing current, and hardfacing layers were selected as independent input parameters while impact resistance of the weld deposit was the output response. Furthermore, the optimal conditions of hardfacing process were two hardfacing layers, a current of 120 amp, and a travel speed of 200 mm/min. Microhardness profile was constructed to identify the depth of hardfacing layer(s). In addition, the chemical compositions of the hard weld deposits for nine specimens were achieved. |
